They're on a lot more bikes than that. Aside from overheating from heavy use they work just fine. Like all rear brakes, they are safer when paired with a front brake.
Rear wheel brakes in general are limited in effectiveness by the traction on the rear wheel. Even cheap coaster brakes can lock up a rear wheel, and at that point you're at the maximum braking power possible. A fancier coaster brake will have the same limitation; about all you can hope for is that it will dissipate heat more effectively and thus maintain its relatively feeble braking power longer than a cheaper model.
